【摘要】：均质油田储集层分布稳定,油层水驱前缘均匀,油井间开采差异小,注水开发效果好,因此,将油田单井平均产油量和产水量作为参考值,利用单井产油量偏差累加生成和产水量偏差累加生成,可以建立二维油井新分类方法——累计偏差系数法。若油田储集层非均质性较强,不同物性的储集层水驱效率存在较大差异,则需在均质油田油井分类方法的基础上对偏差进行物性校正,建立非均质油田油井分类方法——累计非均质系数法。利用油井新的分类方法能将油井划分为不同生产特征的4类井,也能连续性地展现单井的产状变化过程。油井分类新方法改变参考值为单井配产或上年末油井产量,可跟踪检查油井配产执行情况和老井调整效果评价,而且划分的4类油井生产特征差异突出,易于对生产不利因素形成调控对策。经玉果油田应用,效果较好,值得其他油田借鉴。
[Abstract]:The reservoir distribution in homogeneous oilfield is stable, the front edge of reservoir water drive is uniform, the difference of production between wells is small, and the effect of water injection is good. Therefore, the average oil production and water production of single well are taken as reference values. A new two-dimension oil well classification method, accumulative deviation coefficient method, can be established by means of cumulative generation of oil yield deviation and cumulative deviation generation of water yield in single well. If the reservoir heterogeneity is strong and the reservoir water drive efficiency of different physical properties is quite different, it is necessary to correct the deviation on the basis of the classification method of homogeneous oil wells. The cumulative heterogeneity coefficient method is established for the classification of oil wells in heterogeneous oil fields. By using the new classification method, the oil wells can be divided into four types of wells with different production characteristics, and the process of occurrence and variation of single wells can also be continuously demonstrated. The new method of oil well classification can change the reference value to single well production or oil well production at the end of last year, and can track and check the performance of oil well distribution and the evaluation of adjustment effect of old well, and the production characteristics of 4 kinds of oil wells are different obviously. It is easy to control the unfavorable factors of production. By the application of Yuguo Oilfield, the effect is better, and it is worth learning from other oilfields.
